- 8 x^{2} - 15 + 22 x = 0

x = \frac{5}{4}, x = \frac{3}{2}

Decimal Notation

x = 1.25, x = 1.5

Solution steps

- 8 x^{2} - 15 + 22 x = 0

Write in the standard form

a x^{2} + b x + c = 0

- 8 x^{2} + 22 x - 15 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 22 \pm 2 2 ^{2} - 4 ( - 8 ) ( - 15 )}{2 ( - 8 )}

2 2^{2} - 4 (- 8) (- 15) = 2

x_{1, 2} = \frac{- 22 \pm 2}{2 ( - 8 )}

Separate the solutions

x_{1} = \frac{- 22 + 2}{2 ( - 8 )}, x_{2} = \frac{- 22 - 2}{2 ( - 8 )}

x = \frac{- 22 + 2}{2 ( - 8 )} : \frac{5}{4}

x = \frac{- 22 - 2}{2 ( - 8 )} : \frac{3}{2}

The solutions to the quadratic equation are:

x = \frac{5}{4}, x = \frac{3}{2}

25 x^{2} + 60 x + 36 = 0

(\frac{b ^{7}}{4 ^{5}})^{- 3}

27 s^{3} + 1

x^{2} - 20 x - 125 = 0

2 x + 4 (x - 1) = 3 (2 x + 1) - 2 (x - 1)
